only wake on interupt..

markjgabb

Been a while

getting back into the swing of things finally after a few year hiatus ive started building up my nodes again..

so something simple to get me back in the swing..

Im building a sensor that is literally just a momentary button
should only wake on interrupt....
but i cant for the life of me work out/remember how to get it working in practice.
sensor will be built on easy newbie PCB

Long Term goal is to create using a 3D printers a cover for my existing light switches to put over the top as a toggle so if lights are on turn them off if they are off turn them on, but to have it in a case that is easy to remove incase i have issues, and can get back to the untouched orgiginal light switches underneath

ok thanks for that

so i have modifed as the following....

by the look of the alteration,

i can just put a momentary switch in place between vcc and D3 with a resistor in line and be done with it?

Try it and see! ;)

You might not need the sleeptime either as that was used as a heartbeat to make sure the node was still up and running. It also helps with graphing the output to see where motion was not detected for a while.

markjgabb

ok so yeah it does work....but i think its too sensitive

i used d2 in the end for the board im using

but the node seems to trigger every time i even wave my hand near it....

Literally, node is currently setup with two wires you have to touch together to make the switch. when i wave my hand over it it activates
im guesing i need to put a resister in place to decrease the sensitivity? currently its just a wire between 3.3 on a pro mini and the d2 wire

mfalkvidd

@markjgabb yes, without a pull-down or pull-up resistor, the pin will be floating and not have a defined state.

skywatch

as @mfalkvidd said, you need a resistor between D2 and ground if the switch is connected between D2 and VCC(5V/3.3V). Higher value resistors will reduce current flowing but that's not a big consideration for momentary button presses.

markjgabb

Perfect. Tha is for that works great... Interesting thought though with how sensitive it is...

I was actually just waving my hand near it. Possibly 2-3 inches away from the wires....

Could be used as something like a plate you slap with your hand

mfalkvidd

@markjgabb yes, that's exactly how touch-based buttons work (and your phone's touchscreen)

markjgabb

ok stuck now...

it works once...
it wakes up each time and send the command
but in domoticz im using a push on button with a off delay.....
domoticz is ignoring the sensor after the first on, because the sensor isnt available anymore to receive the command....

do i possibly need the sensor to send an on command, wait a moment then send its own off command again?

zboblamont

@markjgabb Domoticz should display a binary On/Off according to what it is sent, so suggest looking at the Domoticz log for incoming messages, I suspect the OFF is not being sent. Why you are using a Domoticz switch with an off delay I don't understand, a simple on/off is what I use.
In your modified @skywatch sketch the loop contains battery measurement batM() which itself incorporates a half second delay and Serial.print, suggest rem that out in the loop for now leaving the main loop to work with perhaps a 5 or 10ms delay if the switch is not debounced electrically.

A momentary rather than latching switch allows a very fast change of state in the region of milliseconds, quite different to a real world device running seconds/minutes/hours in one state or the other.
In your case you are looking at the interrupt as CHANGE, then reporting the digital state of the pin, any old toggle or light switch would do.

markjgabb

yeah i possibly havent been ecactly clear on that

Scenario is that when i walk into a room i dont always want to ask google to turn on or off all the lights in the room.
so i plan on having wall mounted momentary switches, which their sole purpose is to if the lights are on, turn them off and if they are off turn them on....

so i had planned to use a momentary switch so that no one in the house became focused on if they were off or on, but just push them to get the opposite of current state

In domoticz i was going to use a push on button with a dzvents script so that any time the push on on button became on it would toggle the opposite of whatever the state of lights in the room in...

obviously a bit more logic is needed in case some lights are on and others off....

As per advice i have shortened off the times for delays and have taken out the serial prints on the battery monitor

@markjgabb when the node is sleeping, it cannot receive messages from Domoticz.

@markjgabb Wasn't thinking about shortening the battery read but // it out in the loop meantime as it is only a local serial output. Whatever..

Ok on the intent, then what you are doing is "illogical", you are reporting the state of the switch not the condition of the light.
What you need to do is toggle a separate logic parameter on the Node for a LOW interrupt at the Node, switching ON/OFF the light, report that separate logic state to Domoticz then go to sleep... The interrupt only initiates the action, the Node reports and stores the current state until the next interrupt, Domoticz tells you the last reported state.
Whether you control the light at at the button switch Node with a latching relay or command a separate Node is up to you, but Domoticz only reports the last known state...

@zboblamont
haha ok so i went right back to the begining of what you said and got it working now (code below)

cut back all unneccicary steps and really locked down what was going on... i can always add back battery part later

however now when it comes back online after 5 minutes for heart beat it keep sending a switch command to domoticz...

im guessing this is due to the issue where the state is being reported differently after it going to sleep as soon as action is performed....

// Enable debug prints
#define MY_DEBUG

// Enable and select radio type attached
#define MY_RADIO_RF24

#define DIGITAL_INPUT_SENSOR 3   // The digital input you attached your motion sensor.  (Only 2 and 3 generates interrupt!)
#define CHILD_ID 1   // Id of the sensor child


#include <MySensors.h>

unsigned long SLEEP_TIME = 298000; // Sleep time between reports (in milliseconds)


// Initialize motion message
MyMessage msg(CHILD_ID, V_TRIPPED);

void setup()
{
    pinMode(DIGITAL_INPUT_SENSOR, INPUT);      // sets the motion sensor digital pin as input
}

void presentation()
{
  sendSketchInfo("Lounge Multi", "3.0");
  wait(100);
  present(CHILD_ID, S_DOOR);
}

void loop()
{
  // Read digital motion value
   bool tripped = digitalRead(DIGITAL_INPUT_SENSOR);
   //Software debounce.....
   //wait(25);
   //bool tripped1 = digitalRead(DIGITAL_INPUT_SENSOR);
   //if (tripped == tripped1){}
   //send(msg.set(tripped?"1":"0"),true);  // Send tripped value to gw
   
   if (tripped == HIGH){
   send(msg.set(tripped = 1),true);
   }
   else if (tripped == LOW){
   send(msg.set(tripped = 0),true);
   }
  
  // Sleep until interrupt on motion sensor. Send update every ten minutes.
  sleep(digitalPinToInterrupt(DIGITAL_INPUT_SENSOR), CHANGE, SLEEP_TIME);
}

skywatch

@markjgabb I used the trigger data for a 'heartbeat' so that it looked 'normal' on a graph and the graph updated regularly (otherwise it only updated on a change and that can be a long time indeed for some windows)!

The solution might be to immplement the MySensors Heartbeat instead.

Just put " sendHeartbeat(); " without the quotes in the sketch main loop. You may still get messages about status, I am not sure as I use MyController for my set-up and never used domoticz
.
If so you can try and set a memory for the status and only send the tripped message if the status of the last_tripped_status (or whatever you want to call it) has changed.

I believe that the relay sketches in 'build' page use a similar approach from memory.

Here is a strong hint of how to do it..... :)

 if (tripped == HIGH && last_tripped == LOW){
   send(msg.set(tripped = 1),true);
last_tripped = HIGH;
   }
   else if (tripped == LOW) && last_tripped==HIGH{
   send(msg.set(tripped = 0),true);
last_tripped = LOW;
   }

You need to assign a type bool to last_tripped somewhere and initialise it.

@markjgabb "..cut back all unneccicary steps and really locked down what was going on.." was indeed the idea.

What I went on to explain is than you are reporting the state of D3 which goes HIGH/LOW/HIGH via the button, not the light. The critical difference between @skywatch and your install is movement detection maintains a value, your button does not.

If you create a variable before the loop, say boolean lightswitch=false; (presuming that the light is ON when you program it) this variable will be changed and reported to Domoticz in the loop.
Top of the loop you toggle the "lightswitch" value, first time it will switch false to true, report in the "lightswitch" value then go to sleep.
Bottom of the loop your " sleep(digitalPinToInterrupt(DIGITAL_INPUT_SENSOR), CHANGE, SLEEP_TIME); should trigger on a LOW, as this is the momentary state of D3 ONLY when the button is pressed.
Your next button press activates the loop, toggles "lightswitch", reports and goes back to sleep, at least two years on a pair of AA cells.

Were it I doing this there would be a mains powered indicator on the switch plate which cuts out when the light is on, A- To find the switch in the dark, B-To provide an indicator which can be used to verify the actual state of the light to ensure it stays in sync (Murphy's Law).
I don't see the point of using heartbeat as it is not a security device, and only fire the battery reading mosfet every X loops.

only wake on interupt..
